Lucas Bishop is a mutant from the 22nd century that traveled into the past, becoming a member of the X-Men, and later, the Uncanny X-Force. He has the power to channel kinetic energy, releasing it generally through beams of energy.

He started out as a good guy. But, from what I hear, he was always meant to be a bad guy. From the future, in love, in his own way, with Xavier's dream, and determined to protect it by "any means necessary." A guy like that could be very dangerous, and or very loyal. He acts as if the fate of the future rests in his every move. The embodiment of "Desperate men do desperate things in desperate situations". He is a very serious character. Personally, I think he suffers from PTSD. Whatever happened to him in the future, it was not a happy time. Anything he can do to prevent that future he came from, he will do it, with no hesitation. If he is out to get you, you better hope you got someone like Cable with you. Otherwise...
